a few changes
Well, after getting home, I made some changes... here's the "final for now" system (pardon the reflections - had the wife take these for me since I'm now back in Afghanistan):
Subjective, non-technical observations (I'll label these "observations" since my expertise is not quite to the level to call this a “review.”). Another caveat, I only had 2 weeks to set up and spend time with the system. Really, only a few days with the Marantz AV-7005 as I installed it shortly before I left.
Went from Yamaha RX-V667 to RX-A2000 to Marantz AV-7005. Why?
I did not feel the Yamaha pre-outs were adequate to push the Yamaha P2500S (pro amps). Noticed a significant difference in output from the Marantz as a preamp for the P2500S amps (using unbalanced XLR to RCA cables by Hosa). I did not notice any buzzing or noise issues from the AV-7005.
Dr. Mark (TLS Guy) recommends staying away from balanced cables for short runs but, for the minimal cost, I may try these and see if I get any noise. If no extra noise, I can obtain more pre-out voltage (2.4 V balanced vs 1.2 V unbalanced).
Of note, comparing the RX-V667 with the RX-V667 + Yamaha P2500S amps I noticed a great deal more bass and the sound was much more “full and dynamic.” Some might say “duh” but this was an interesting comparison for me. It showed me the big difference an amp can make. Also, these (Salk SongTowers & Center) were run full range (did not use the AVR crossover). I did not test the RX-A2000 without the amps.
I choose the 2 x P2500S pro amps over 3 x Outlaw audio M2200 mono amps because I heard a slight (not significant) buzz when using the M2200 amps with the Yamaha RX-V667. The Yamaha amps are nearly silent. Did not do a listening comparison after I noticed the buzz.
Sound:
I don’t have anything for comparison besides the TV speakers and headphones. In short, the ST are very impressive but perhaps a little more laid back than I hear in some of my headphones. I’ll do more headphone comparisons when I get home since I have no other nice systems with which to compare. Our high end stores in Alaska are rather limited.
Aesthetics:
My wife, who has very little interest in all things audio made several observations:
1) The SongTowers “really looked good.”
2) After going through the RX-V667 and RX-A2000 (both of which I think look pretty cool, especially the RX-A2000). When she saw the AV-7005 she commented “Wow, that receiver looks nice!.” Unbelievable.
Rhythmic F12:
Adequate for our room and uses. I’d like to try out some software (at some point) to see what type of frequency response I’m getting. I can tell at some frequencies the bass is louder than others but I’m pretty sure this is placement related (did not crawl for bass or really do any moving of the sub as time was limited).
Problems:
Cable management! The Amish can make great looking furniture but I should have allowed more room (and holes) for running/hiding cables and wires. For our retirement system, I’ll use a closet and a Middle Atlantic rack.
Had a devil of a time getting the front handles off the P2500S pro amps and then getting them back together. Removal is not recommended if you have the room to leave them on!
After I did one, I figured it would be just as much trouble to put the handles back on as to remove the handles from the 2nd so I removed the front handles from both amps.
Overall:
Best sounding system I have ever owned. I’ll do some tweaking when I get home. For now, am running the Audyssey recommended large settings for LCR. Possible changes - going to an AVR only for the living room & moving the AV-7005 + P2500S amps to my music-only setup to cut down on the cables.
Next project: 2.0, 2.1 or 2.2 music only system with perhaps a small monitor for PC integration. JTR, B&W, PMC, Yorkville Unity, and Gedlee are on the short list.
Thanks Audioholics for all your time and input!
